YMF740C DS-1L OVERVIEW YMF740C (DS-1L) is a high performance audio controller for the PCI Bus. DS-1L consists of two separated functional blocks. One is the PCI Audio block and the other is the Legacy Audio block. PCI Audio block allows Software Driver to handle maximum of 41 concurrent audio streams with the Bus Master DMA engine. The PCI Audio Engine converts the sampling rate of each audio stream and the streams are mixed without utilizing the CPU or causing system latency. By using the Software Driver from YAMAHA, PCI Audio provides 32-voice XG wavetable synthesizer with Reverb and variation. It also supports DirectSound hardware accelerator, Downloadable Sound (DLS) and DirectMusic accelerator.
